What's wrong with this setup is the substrate on which you have positioned the drop is "dirty and unclean" meaning it is not being dampened by the solution. This action can be corrected by comprehensively cleaning the substrate where the drop will be positioned.

Newton’s second law of motion is F=ma A net force of 60 N north acts on an object with a of 30 kg. Use Newton’s second law of mo

Luda [366]

<u>Answer:</u> The acceleration of the object is $2m/s^2$ . If net force increases, acceleration will also increase and if mass increases, the acceleration will decrease.

<u>Explanation:</u>

Force is defined as the product of object's mass and acceleration.

Mathematically,

$F=ma$ ......(1)

or,

$a=\frac{F}{m}$ .....(2)

where,

F = Force exerted on an object = 60N

m = mass of an object = 30kg

a = acceleration of the object = ?

Putting values in above equation, we get:

$a=\frac{60kg.m/s^2}{30kg}=2m/s^2$

The acceleration of the car is $2m/s^2$ .

From equation 2, it is visible that acceleration is directly proportional to force. This means that \if force increases, acceleration also increases.

And acceleration is inversely proportional to mass of the object. This means that if mass increases, the acceleration decreases.

Hence, if net force increases, acceleration will also increase and if mass increases, the acceleration will decrease.
